Answer:
Option C -
Step-by-step explanation:
To find : Which polynomial is in standard form?
Solution :
The standard form of a polynomial is defined as each term in order of degree is written from highest to lowest.
The degree is the power of a variable.
Now, we check the order of each polynomial.
A)
The degree of the polynomial is 5,7,3,1 not from highest to lowest.
So, No the polynomial is not in standard form.
B)
The degree of the polynomial is 5,1,2 not from highest to lowest.
So, No the polynomial is not in standard form.
C)
The degree of the polynomial is 5,2,1 is from highest to lowest.
So, Yes the polynomial is in standard form.
D)
The degree of the polynomial is 2,2,4,7 not from highest to lowest.
So, No the polynomial is not in standard form.
Therefore, Option C is correct.
The standard form of the polynomial is

Answer:
Bethanie and Laney walked a total of = 0.66 miles or (th of a mile)
Step-by-step explanation:
Bethanie walked 3/10th of a mile
Laney walked 36/100th of a mile
Lets divide and convert them to decimal:
3 divided by 10 gives us 0.30
36 divided by 100 gives 0.36
Total they walked:
0.30 + 0.36 = 0.66 miles
That would be (in fraction):
66/100 = 33/50 of a mile
6. When we multiply two surdic integers, we can leave it into one big surd.
For instance, if we have:
, we can simplify it down to one uniform square root sign, 
.
So, we can say:
, which is a rational root, because the square root of 36 can be converted into an integer, namely 6 and -6.
Hence, it is a rational root.
7. The summation, on the other hand, cannot be simplified any further, so it will stay as irrational. This is because √2 is already an irrational root, and adding it onto a number that is rational will stay as irrational.
8. Once again, the summation cannot be simplified. We can only simplify by factoring like terms. Hence, this must be irrational.
9. Even if it is in fractional notation, √5 can never be a rational number because no two integers when multiplied by itself will give 5. So, even if it is written in fractional form, they cannot be rational if there is an already irrational term in it.
For instance, if we have:
So, we can say:
Hence, it is a rational root.
